目的:探讨肾上腺转移瘤的PET/CT表现,提高其诊断及鉴别诊断水平。材料与方法:结合文献对肺癌、乳腺癌、胆管细胞癌等患者进行PET/CT检查发现的肾上腺转移瘤进行回顾性分析。结果:肾上腺转移瘤30例,检出33个转移灶,单侧27例,双侧3例。影像学特征:肾上腺肿大,浅分叶,密度不均匀;PET显示肿大的肾上腺有18F-FDG示踪剂的高摄取,浓聚程度(SUV值3.4～6.4),延迟扫描后(3.9～10.1)。结论:PET/CT对检出肾上腺转移瘤有很高的价值。
Objective: To investigate the PET / CT findings of adrenal metastases and to improve their diagnostic and differential diagnosis. MATERIALS AND METHODS: A retrospective analysis of adrenal metastases detected by PET / CT in patients with lung cancer, breast cancer and cholangiocarcinoma was performed in combination with the literature. Results: Adrenal metastases in 30 cases, 33 metastases were detected, unilateral in 27 cases, bilateral in 3 cases. Radiographic features: Adrenal enlargement, shallow lobes, uneven density; PET showed enlarged 18F-FDG tracer in the adrenal glands with high uptake and concentration (SUV 3.4 ~ 6.4) 10.1). Conclusion: PET / CT is of great value in detecting adrenal metastases.
